Overview of New EPA Superfund Groundwater Guidance and Tools - November 4, 2014, 12:30PM-1:30PM EST (17:30-18:30 GMT). Groundwater remediation is a component of more than 90 percent of active Superfund sites and achieving remedial action objectives can take years or even decades. Collectively federal agencies, states and potentially responsible parties (PRPs) spend hundreds of millions of dollars each year to address contaminated groundwater. Given the importance of groundwater, the challenges and costs associated with groundwater remedies, the EPA has recently issued a new suite of guidance and tools to help focus resources on the information and decisions needed to effectively complete groundwater remedies and to ensure that these remedies protect human health and the environment. This 1 hour webinar will describe the benefits and utility of the following recently issued EPA guidance and tools: Guidance for Evaluating Completion of Groundwater Restoration Actions (Nov. 2013), Groundwater Remedy Completion Strategy (May 2014), Recommended Approach for Evaluating Completion of Groundwater Restoration Remedial Actions at a Groundwater Monitoring Well (Aug. 2014), and Groundwater Statistical Tool (Aug. 2014). The above EPA groundwater guidance and other resources are available on EPA's website at Participants may also be interested in the CLU-IN seminar on Evaluating Completion of Groundwater Restoration Remedial Actions on November 12, 2014.

ITRC Project Risk Management for Site Remediation - November 13, 2014, 11:00AM-1:15PM EST (16:00-18:15 GMT). Remediation Risk Management (RRM) is a course of action through which all risks related to the remediation processes (site investigations, remedy selection, execution, and completion) are holistically addressed in order to maximize the certainty in the cleanup process to protect human health and the environment. Remediation decisions to achieve such a goal should be made based on threshold criteria on human health and ecological risks, while considering all the other potential project risks. Through this training course and associated ITRC Technical and Regulatory Guidance Document: Project Risk Management for Site Remediation (RRM-1, 2011), the ITRC RRM team presents tools and processes that can help the site remediation practitioner anticipate, plan for, and mitigate many of the most common obstacles to a successful site remediation project. Examples of project risks include remediation technology feasibility risks; remedy selection risks; remedy construction, operation and monitoring risks; remedy performance and operations risks; environmental impacts of systems during their operation; worker safety risk, human health and ecological impacts due to remedy operation; as well as costs and schedules risks including funding and contracting issues.

The goal of this webinar is to inform Superfund RPMs, and others, of the RCRA process be it regulation, guidance or personal interactions between the programs. Case studies from Superfund RPMs and RCRA Corrective Action PMs will provide real world examples of this interaction. In addition, a high-level overview of RCRA is provided to set up each case study example. For more information and to register, see

Porewater Concentrations and Bioavailability: How You Can Measure Them and Why They Influence Contaminated Sediment Remediation - Sessions II, III, and IV - November 19, December 1 and 15, 2014. NARPM Presents and Risk e-Learning are offering a four-part webinar series to help you understand why, how, and when to measure porewater concentrations and bioavailability as part of contaminated sediment assessment and management. Hosted jointly by the EPA Contaminated Sediments Forum and the National Institute of Environmental Health Science's Superfund Research Program, this webinar series will also focus on the use of passive sampling devices (PSD) and what they tell us about contaminant bioavailability. Previously held as a course at the National Association for Remedial Project Managers (NARPM) Training Program meeting, the webinar series features experts in the field of porewater and bioavailability and includes lectures and case studies, including practical tips to maximize the utility of porewater and bioavailability measurements. Presenters will explain the basics of chemical fate, transport, and uptake, with a focus on porewater as a key route of exposure and a strong indicator of bioavailability. PSDs are a promising technology for measuring porewater concentrations and assessing bioavailability, particularly for common sediment contaminants such as polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), chlorinated pesticides, and dioxin-like compounds. The webinar series will include information about direct measurements of porewater, such as centrifuging sediment samples or Henry Samplers, which may also be used and are particularly useful for measuring metals.

Petroleum Vapor Intrusion: Fundamentals of Screening, Investigation, and Management. Petroleum Vapor Intrusion (PVI) is the process by which volatile petroleum hydrocarbons (PHCs) released as vapors from light nonaqueous phase liquids (LNAPL), petroleum-contaminated soils, or petroleum-contaminated groundwater migrate through the vadose zone and into overlying buildings. This ITRC guidance document uses a scientifically-based approach to support improved decision making at potential petroleum vapor intrusion (PVI) sites by employing an eight-step process. By applying this approach, decision makers can confidently screen out sites, and therefore focus limited resources on the small fraction of petroleum-contaminated sites that warrant vapor control or additional site management. This ITRC guidance complements the ongoing work of U.S. EPA Office of Underground Storage Tanks (OUST) in addressing the PVI pathway (October 2014, 388 pages).

Research Brief: Measuring Vapor Intrusion to Estimate Underground Contamination. Vapor intrusion involves the movement of contaminants from beneath a home or a business up into the air inside the building. The vapor source is typically groundwater that contains low to moderate concentrations of either chlorinated solvents, such as trichloroethylene (TCE), or petroleum-related compounds, such as benzene. The importance of measuring vapor intrusion is that even in low concentrations, long-term exposure to these volatile chemicals may pose an unacceptable risk of chronic health effects. Scientists from the Brown University Superfund Research Program have taken a step toward providing a simpler, accurate screening method to determine whether chemicals in underground sources are seeping into buildings and contaminating indoor air. The researchers developed process models to predict the concentrations of vapors that enter indoor environments. Results from the process models were consistent with advanced computer modeling techniques. For more information, see
